From NASA’s official return to spaceflight site:
Space Shuttle Program Deputy Manager Wayne Hale has announced more troubleshooting is necessary to determine why an Engine Cut-Off sensor gave intermittent readings during Wednesday’s attempted launch of Space Shuttle Discovery.
The monitoring device protects a Shuttle’s main engines by triggering them to shut down in the unlikely event fuel runs unexpectedly low. NASA launch regulations require that all four sensors work properly for liftoff. (To view a graphic showing the sensor’s location at the bottom of the External Tank, click here.)
Hale predicted more information could be available Friday, after NASA and contractor engineering teams across the country have had more time to analyze data and come up with a more definitive plan.
The STS-114 crew will remain at Kennedy Space Center for the time being, continuing preparations, repeating some training and even taking some time to relax.
The good news is for the time being, the STS-114 crew is staying in FL, so there’s hope of a launch that isn’t too far in the future.
